I just added some entries in my iCal on my MBP (SnowLeo) and was thinking that I should try to sync my BB 8900. I had never done this before.

Anyway, I tought that the new entries made by me on my mac also would be on my 8900 after sync, right? After my sync, there is only those entries that were on the phone originally, none of those I made in iCal.

Is there something I´m doing wrong?

You need to make sure you have BlackBerry Desktop Manager set for 2-way sync in Calendar, not one-way. You should also have your BB set to save calendar appointments for longer than the minimum 15 days, or even 30 days, or else the BB will start deleting your old appointments in iCal.

It is set for two-way, and the appointments were in the future, so they shouldn't be deleted because of auto-delete.

Great post!
